Q 2650280114.     (a) Calculate `E_text(cell)^°` for the following reaction at `298` `K` :
`2Al_((s)) + 3Cu^(+2)(0.01M) → 2Al^(+3)(0.01M) + 3Cu(s)`
Given: `E_(cell) = 1.98V`
(b) Using the `E^°` values of A and B, predict which is better for coating the surface of iron` [E°(Fe^(+2)//Fe) = -0.44V]` to prevent corrosion and why?
Given: `E° (A^(+2)//A)=-2.37 V: E°(B^(+2)//B)= -0.14V`
